Thanks for the fix! 

From an ical perspective, the time zone block should encode the DST rules for the locale under a single label. The old database only gave us an integer offset, so the output we presently generate is very primitive (and slightly wrong). It sounds like the new DB is much more intelligent about this kind of thing. Hopefully, my code refactor of the agenda code on Saturday will result in doing this correctly.
